Kenyan sand boa stargazing?

[Bogertophis]

Congratulations...I suspect you're a "helicopter snarent". ALL snakes look up now & then...that doesn't mean they're sick, much less stargazing. No doubt your
vet would happily take your money to check him out...especially as an "emergency", but most likely you're just worried for nothing. Snakes are ALLOWED to look up,
it's in their contract... And when they're hungry, many will try to climb the walls in search of food...they rely on scent, which in MOST cases is coming from the TOP of their enclosures.

If that was my snake, I'd gently hold him so his face was near my ear, & listen for crackling, whistling, squeaking sounds...those can indicate an RI. Also bubbling
and excessive saliva in or near the mouth, & struggling to breathe (open mouth) since they cannot cough away excess secretions.

I'd also suggest assessing his overall coordination & strength...if that seems normal (as I suspect it will), he's not sick, just nosy (or hungry). Snakes with IBD are usually quite obviously sick...if you turn them on their back, they're unable to right themselves...they may have trouble holding on to things, & seem unsteady, as if they're dizzy, and move abnormally with poor coordination.
